As possíveis relações entre desenvolvimento moral e uso de crack por adolescentes

The dependency of psychoactive substances whether licit or illicit, among adolescents is a topic that has aroused much discussion today. One of the psychoactive substance that has caught the attention of authorities and experts, its potential dependence, increasing the number of addicts and speed with which triggers the human degeneration is the crack (a derivative of cocaine - Erythroxylon coca), used via the smoked administration. Understanding the phenomenon of increasing their use requires an analysis of the concepts of addiction throughout history, current research encompassing scientific findings in epidemiology and statistics involving several types of pharmacological substances, and especially the analysis of data related specifically to crack the focus of our theme. In order to contribute to ongoing discussions and offer possible alternatives for effective intervention, especially in schools, we conducted a survey that sought to find evidence of a possible relationship between crack use and moral reasoning. Since our work specifically theoretical nature, we use to reach our goals, assumptions, two researchers in the concept of human morality: Jean Piaget (1994) and Lawrence Kohlberg (1992) both traveling within the proposed cognitive-evolutionary human development. For an understanding of the proposals of these two researchers, we use research to (Lepre, 2005), as guiding thesis of this work. The results presented indicate that adolescents who use crack are very close to a level of moral reasoning pre-conventional and conventional, although it is important to state that more accurate results require further research on the subject, including those involving field research. Yet we can conclude that prevention must go through a dialogue that privileges the moral education as possible means of effective intervention against the use of crack, allowing the construction of autonomy...

Usando o ATSP na Modelagem do Problema Integrado de Produção de Bebidas

Neste trabalho, propomos um modelo integrado de dimensionamento de lotes e programação da produção monomáquina para uma fábrica de refrigerantes de pequeno porte. As decisões de dimensionamento foram baseadas em um modelo encontrado na literatura e as decisões de sequenciamento foram modeladas utilizando restrições do problema do caixeiro viajante assimétrico. Para a validação do modelo proposto foram feitos testes computacionais com exemplares gerados aleatoriamente, e também exemplares baseados em dados reais obtidos da literatura. Os exemplares foram resolvidos pelo método Branch-and-Cut incluído no pacote computacional CPLEX 10.0. Os resultados mostram que o modelo proposto representa o planejamento da produção em fábricas de bebidas monomáquinas e que, em algumas situações, produz resultados melhores que o modelo da literatura.

Inclusão escolar com apoio: uma análise do serviço do ensino itinerante

We investigated the process of inclusion in the school common areas, tracking the performance of a traveling school teacher (teaching support service specialist), type of service in Special Education, as a support to the school's educational proposal. Objectives: To identify, describe and analyze the performance of itinerant school teacher in a school of mainstream school, with students and their teachers, to analyze the perception of two teachers of the common teaching about the process of integration of pupils with special educational needs in their classes; examine the roles and responsibilities of itinerant school teacher through an exploratory qualitative approach. Participants: an itinerant school teacher, two teachers and two of the common teaching students with special educational needs included in mainstream school. Observations were made weekly at the school over a period of six months, semi-structured interviews with teachers and document analysis. The results showed different facets of roaming at the intersection with the common teaching among them may be noted that acts as a parallel system in the common school, creating a gap between them which may compromise or disadvantage of the dynamic performance of service support, but this gap is overcome at critical times facing the mainstream school, where this service benefit the child's learning process and promotes their inclusive education policy.

De um falsário a outro, de patranhas viageiras a legados críveis (século XV)

In the 15th and early 16th centuries, when traveling eastward and westward no longer proved extraordinary, travel writings, such as those of Marco Polo or Jean de Mandeville, were printed and reprinted and have been in the world of exchanges and acquisitions both in Portugal and in other parts of Europe. However, although they have played a key role in defining foreign worlds for Europe, reflecting the aspirations of their time and providing news about the universe to be discovered, these reports do not always necessarily tell of trips that were actually taken. Several of them, on the contrary, do no more than draw together, for contemporary readers, passages of interest taken from other writings; passages which, based on their regularity and frequency, would allow for a narrative staged as travel to be taken as truth for contemporaries and immediate successors. In the Iberian Peninsula of the late 15th century, an account written by an author about whom nothing is known, Gomez de Santisteban, who defines himself as a companion of Prince Pedro on a supposed trip to the Holy Land, was among those reports integrated into the description and the perception of the land being discovered. The driving question of this paper is, therefore, how Santisteban, though he wrote memories of trips that he did not take, achieved credibility like those travelers whose trips have been recognized as authentic.

An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes

In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found to be problematic when applied to plastic pipes due to the high damping within the pipe wall and the surrounding medium. This is responsible for the leak signal not traveling long distances. Moreover, the leak energy in plastic pipes is generally located at a narrow frequency range located at low frequencies. However, the presence of resonances can narrow even more this frequency range. In order to minimise the influence of background noise and resonances on the calculation of the time delay estimate, band-pass filters are often used to supress undesirable frequency components of the noise. The objective of this paper is to investigate the influence of resonances in the pipe system (pipe, valves, connections and hydrants), on the time delay estimate calculated using acoustic signals. Analytical models and actual leak data collected in a bespoke rig located in the United Kingdom are used to investigate this feature.

Localizador de faltas por ondas viajantes em linhas de transmissão

It is important to ensure smoothly operation of a transmission line, sending energy to the consumption centers with minimal interruptions and safer. With this necessity, the fault location techniques have grown, in order to mitigate the impact of the fault and its correction can be more quickly and accurately. This paper presents a comparison between two different techniques of fault location, the fault location by impedance method, which uses the line parameters, the impedance per distance, voltage and current signals, and the other is the traveling wave method, which uses only a very fast analysis of time, synchronization and length between the line ends, do not using voltage and current values, but the temporal perception of the fault. Using travelling waves fault detection makes the previous knowledge of line parameters obsolete, which helps a lot network technicians and engineers with a quick and easy analysis. The methods are simulated in ATP Draw software, so both algorithms can be evaluated for their effectively and accuracy
